Cable with turn back protector

Abstract

A turn-back protector securable within the return bend of a multi-conductor sheathed cable to limit the minimum radius of a return bend in the cable thereby protecting the cable from too severe bending. The protector is particularly useful in connection with butt cable splices and cable dead ends, whether under ground or above ground.

I claim: 
     
       1. A device installed within a return bend of a cable to rigidly support the return bend and prevent bending of the cable through an arc having less than a predetermined minimum radius, said device comprising: a. a circular disc of rigid material provided with an external circumferential groove having a width not less than the diameter of said cable and an inner radius not less than the inner radius of said return bend in said cable;   b. said circular disc being installed in said return bend in said cable with said return bend in said cable disposed in said external circumferential groove in said circular disc;   c. said circular disc being provided with circumferentially spaced openings inwardly of the periphery thereof; and   d. at least two tie means inserted through said openings in said circular disc at points spaced apart circumferentially of said circular disc and wrapped around the periphery of said circular disc and said return bend in said cable, whereby to immovably secure said circular disc in said return bend of said cable.   
     
     
       2. A device as defined in claim 1 wherein said disc is formed in two identical halves having abutting central portions in which said circumferentially spaced openings are formed and having spaced, radially outwardly diverging peripheral portions forming said external circumferential groove, said central portions of said disc halves respectively having circumferentially spaced pins and respectively having circumferentially spaced recesses complementary to and snugly receiving said pins to secure said disc halves together.
